SEXUALLY TRANSMITTED DISEASES

INTRODUCTION

According to the Websters’ dictionary, a sexually transmitted disease, or commonly termed STD, can be defined as any of various diseases transmitted by direct sexual contacted that include classic venereal diseases (as syphilis, gonorrhea, and chancroid) and other diseases (as hepatitis A, Hepatitis B, giordiasis, and AIDS) that are often or sometimes contracted by other sexual means (Internet 3). This lab report will be dealing with three specific types of STDs each from a different origin. Information will be given on each STD with reference to their common/scientific names, life cycle, transmission, and other key factors that influence and maintain the existence of the STD. This report deals with what may be everyday termed diseases however, these STDs affect one in four adolescents before the age of eighteen. Though these STDs are so common and spoken of so often, without early diagnosis and treatment they pose a serious and may be, even a fatal treat to someone who is infected and also their sexual partners or just innocent people who have come into contact with an infected person.

Herpes Simplex Virus type 1 (HSV-1)
The viral disease that will be discussed is the Herpes Simplex Virus type 1 (HSV-1). This STD as stated before is a viral disease, of which a virus can be defined as any of various submicroscopic parasites of plants, animals and bacteria that often cause disease and that essentially of a core of RNA or DNA surrounded by a protein coat. Unable to replicate without a host cell, viruses are typically not considered living organisms.
HSV-1 is usually associated with infections of the lips, mouth, and face. It is especially common in children between the ages of one and three years old and may cause lesions inside the mouth and inflamed gums. It causes cold sores or fever blisters and is transmitted by something as simple as oral or respiratory secretions (for example, sneezing or coughing can transmit the virus).
Most people have in one point of their life been affected with the type 1 virus by the age of 20. In addition to oral and genital lesions, the virus can also cause an infection of the eye involving the eyelid, conjunctiva, and cornea. A finger infection called herpectic whitlow affects health care providers because of exposure to lung and mouth secretions during procedures and young children. The herpes virus can also affect the fetus and cause congenital abnormalities.
Infection occurs after exposure to the virus through a break in the skin, or through mucus membranes. There is strong evidence that the virus may be transmitted even when the symptoms are not present. The virus spreads to nerve cells within the body, and then to other mucosal skin surfaces. The virus remains dormant in the body after an active infection and recurrences of the symptoms can take place at a later time. Recurrences may be precipitated by overexposure to sunlight, fever, stress, or certain foods and drugs.
Additional symptoms that may be associated with this disease are enlargements of lymph nods in the neck or groin, vaginal discharge, sore throat and memory loss. Physical findings of blisters may be sufficient to diagnosis the herpes simplex.
With regards to treatment, this all depends on the severity of the infection. Some cases are relatively mild and may not require treatment. Anesthetic mouthwashes such as 2% lidocaine or baking soda may reduce the pain of lesions inside the mouth. Alcohol-based mouthwashes should not be used. Gentle cleansing of skin lesions with soap and water is recommended. Warm baths may reduce the pain of the genital lesions. Oral Acyclovir (Zovirax) may be prescribed to suppress recurrent eruptions. The lesions generally heal on their own in 7 to 10 days however, once infected, the virus stays in the body for the rest of a person’s life and recurrences of active infection may happen.

Chlamydia Chlamydia trachomatis
Chlamydia trachomatis is a bacterium that can cause the STD Chlamydia. A bacteria is any of the unicellular, prokaryotic microorganisms of the class SCHIZOMYCETES which may vary in terms of morphology, oxygen and nutritional requirements, and motility and may be free-living, sciprophytic, or pathogenic, the latter causing disease in plants or animals.
Chlamydia infection is very common among young adults and teenagers. However, many people do not know that they have chlamydia, because although they
